After updating to brand new BIOS from Jan. 19th I cannot boot anymore into Windows 8.1 - always get INACCESSIBLE_BOOT_DEVICE. Tried to repair using a Windows 8.1 USB Stick, no success. Even downgrading to 1.08 did not work as well!

Downgrade to BIOS 1.05 impossible, due to ISO File on www.lenovo.com support is not system compatible, message "Lenovo Group Limited - Invalid system disk; Replace te disk, and then press any key")(The link to the ISO File version 1.05 at the bottom of this page links a non bootable ISO image [URL]....)Also the downgrade to BIOS version 1.08 found here [URL] .... does not work, CD also messages "Lenovo Group Limited - Invalid system disk - Replace ...").

Rewriting BIOS version 2.05 (GNET57WW) does not work (says "BIOS update not necessary").

Embedded Controller Version GMHT25WW (1.10) ME Firmware Version 9.0.22.1467. How to get back my RAID controller?

Both me and a friend of mine have Lenovo W540s. Everything was working perfectly fine with all of our hardware, until today. A BIOS update came out and installed correctly on both of our machines. After this update both of our UltraNAV features on the trackpad are all dead. After that first restart a message appeared "finding new hardware" and it found a generic mouse on the laptop. Now when I try to re-install the UltraNav drivers, it says no hardware found. I tried both the drivers on Lenovo.com and the manufacture's website all with no luck.

I got my W540 recently with windows 8.1 pro on it. but as all engineers worst nightmare windows 8 has hard time with engineering softwares (for my case TIA Portal for PLC programming software which only support windows 7). so i need to have a windows 7. i prefer to keep my windows 8 and have dual boot system with windows 7 added. But i can't install windows 7. initially due to disk type (GPT), then i changed it to MBR without losing my files (which only was possible if i had deleted the recovery partition- now my recovery is on my flash drive). But there are already 4 partitions on the system (1 for C: drive and 3 for recovery and system files which came originally with the product) , how can i install a windows 7? i can't add another partition because that makes my disk a Dynamic disk. i really need windows 7 on my system ASAP.

Using Defender Offline "Beta" as instructed on MS website for Windows8.1. Created the media on a USB drive, then on a CD. Manually selected boot device on the boot sequence page. Followed all the instructions to the letter, but the Defender Offline media won't boot on this new W540, either on USB flash drive, or on the CD drive.

I bought windows 8 .1 machine from factory. Then I had local shop install 8.1 on larger ssd. I just performed latest bios update and now machine will not boot. I am sure this is uefi related but I am not knowledgable in that area. The boot parameter returned to me by the shop was "legacy only" and secure boot was disabled.

I just got a new Lenovo W540. I installed a new Samsung EVO SSD inside to replace the stock mechanical hard drive. I'm now trying to boot from a flash drive to clean install Windows. I've done this so many times before on other laptops and desktops without a problem. For some reason now it will not boot from the flash drive. It shows it as available in the BIOS but it looks like it reads it for just a second and then goes right back to the screen that allows me to choose which drive I want to put to.The same flash drive works fine in other computers to boot to.I did check to make sure the USB drive was not excluded in the BIOS and it is not.

It's been a yeah that i work on this X1 Carbon laptop and no default. I got a windows update yesterday, i did it and my computer powered off naturally. This morning, i cant start it, It boot well, Lenovo sign appear but nothing after. only black screen with blinking underscore.

I have a brand new W540 with Windows 8.1 running. Some Fn-Keys are working, for example Fn+F2 for the volume. But I have some keys which are not working: Fn+F5 or Fn+F6 should change the LCD brightness.

Why these keys are not working? All updates are applied (Lenovo and Windows)...

The W540 has an onboard video card in addition to the NVidia video card. We use AutoCAD and Revit, and will never care for the onboard video card driver. We cannot seem to get the 170 watt Ultra Docking Stations (plural) to work with our W540 Laptops (plural) when selecting the NVIDIA card and using an external monitor. We have updated all the drivers Lenovo has asked us to including the firmware on the docking station. We have followed the instructions to make the change in the BIOS so that the NVIDIA card is only used. We have called Lenovo support twice on two separate occasions. On one occasion, they said we are not the only people to call in about the problem, and that our only course of action is to get another docking station or return the dock to our vendor. Using Windows 8.1, W540 on an ultra dock and using HDMI? Even though I mention HDMI, (because I think it is the main suspect), DVI seems to blue screen the laptop too.

The first think I wanted to do was to create recovery media (I'm going to re-install on a SSD). However, trying to run the Windows 8 "Create recovery media" tool, as sugested by Lenovo, results in the following:

The option "Copy the recovery partition ..." is grayed out, and I can not select it. Pressing Next results in the following:

I get the error in the Title after i tried to flash the latest BIOS update for the Z510. I can press ok and then get into the boot manager but i cant choose anything there. Also I cant boot from a Disk with e.g. XP on it.

I also tried the Inside BIOS crisis mode (fn+r) with the BIOS file on my USB drive but it doesn't work and tries to access the file on the USB drive but boots normally instead to the error again. (Couldn't try it with removed battery as I have to remove the whole back to remove the battery on the Z510).

I just bought Z50-75 with AMD FX7500, 8GB Ram and FreeDOS. I installed Windows 8.1 Pro, and they pulled some drivers during the installation, and I went to Lenovo sight and downloaded all the rest (graphics, camera, etc.), after each installation the computer restarted normally and all was O.K. The last drivers that I saw on the site were BIOS drivers, and I downloaded those to and it started the installation after which it said:"The system will now restart for changes to make effect", and it did, but, it would not boot up after that, all it did was show me this on the screen:

And I tried both of the options (the second one with the Windows CD inside), but it just stays where it is, no effect.

I can enter the bios and change the settings, but none of them seem to work because this is the maximum where it will go, the only difference is when I change from AHCI to Compatible mode, it restarts and than I have a blank screen, I have to use the One button Recovery to get back to this one from the picture above...

I am unable to update the BIOS on the Thinkpad listed below.I have tried to run Boot CD version of the update program (using CD player in dock) and it reports the error:"The system program file is not correct for this system"..The Windows based BIOS update program reports the error (in or out of dock):

"The process does not recognize this system. The process has been cancelled"..The Lenovo support page lists the new BIOS as being appropriate for this model. The BIOS reports the correct model and serial number.I desire to update the BIOS only as part of a software reload / refresh of the laptop. No actual problem with current BIOS to my knowledge.

I recently upgraded my ThinkPad W530 laptop BIOS from version 1.11 (which it shipped with) to the latest, version 2.59.

After doing so, my two 16 GB DIMMS are not only showing up as 8 GB each, thereby cutting my usable memory in half from 32 GB to 16 GB.

I ran through all the normal hardware checks to ensure that one of the DIMMS wasn't bad. I tried each DIMM separately, tried in different slots, etc. They both show up just fine and even pass the memory quick test in the BIOS. Only, they are showing up as 8 GB DIMMs.

Is there a feature in the latest BIOS that would somehow limit this? It was working fine at 32 GB before.

And, unfortunately, there is no reverting back to BIOS v.1.11 from anything after v.2.55. It asked me if I was sure I wanted to proceed...this was the last type of problem I expected to see though. (I also tried reverting back to previous versions of the BIOS that were allowed and it didn't work...

I have bought used x131e 3367. After successful update of drivers (Win8) using System update 5 I decided to update also offered new bios. After flash and restart I can hear only beeps 1-3-3-1. I have tried to find solution to recover BIOS but no luck. Solution with wincrisis does not work for me. I have tried to use e_bcpvpw.exe with $0AG9000.FL1 file but no luck - Source file format not acceptable - missing header!

I just updated my bios on my Z510, and now the only boot options i have is network boot, something that i don't use. I used the bios update tool that Lenovo is distributing from the drivers page for my PC.

My new W540 has the latest bios & software updates. It won't wake up from sleep...or rather the display won't come on. When I push the power button (pulsing green), it goes to solid green and the fingerprint scanner light turns on, but no screen. I scan my fingerprint and the scanner light turns off, but still no screen. The only way to bring it back to life is a long press on the power button and a reboot.

Nothing plugged into any of the ports. It does this regardless of whether it's plugged in or on battery.

I recently bought an X240 and have this shutdown problems. Before it was caused by Norton anti-virus so I uninstalled it, then the laptop was working fine. Now, after some Windows update, it doesn't shutdown again. What is wrong with this laptop?

I have tested the following on 2 identical W540 machines.After installing Windows 8.1, the internal camera is not working. I dont remember if the camera worked before we installed 8.1. I have installed all relevant drivers and updated all windows updates. I have installed all drivers from System update.

I waited a long time for this new W540. Downlkoad all the newest drivers and did all the updates and now this POS will not shut down. Just goes to a black screen and have to hold the power button to force a shut down.

When I try to reboot the screen goes to black right after the home screen with a twirling cursor. Had to send my new W530 back for hard drive failure and now this W540 is screwed, too!
